For this reason, the ladder editor for the OpenPLC is based on LDmicro, a simple Ladder editor/compiler. I'm much stronger with low level programming and hardware design.
#Open source plc ladder logic windows#
Thiago an electrical engineer, my knowledge about high level Windows / Linux programming is limited.
If you want to collaborate, give suggestions, or say anything related to the project, please reply to this post, PM-me or email me. If you want to know more about the project, check this website. The slave boards runs on 328P's and have 485 communication with the CPU. The CPU is an ATMega2560, with USB, ethernet and RS-485 communication. Every board has an ATMega microcontroller and runs the arduino boot loader. The project now has grown into a complex system with 4 boards, but is still based on the Arduino platform. Actually, my first version was just an arduino with some shields that I developed myself, to offer some protection to inputs and outputs.
#Open source plc ladder logic code#
I created a google code page to share my research and made a few friends along the way. So, in 2012 I started building my own open source PLC. The big problem is that there is no open source PLC to date (at least none that would be compatible and do the same thing an actual PLC does), and PLCs are extremely expensive! :~ They can be programmed using a graphical language called Ladder (it is very similar to electric diagrams) and is used in most industries all around the world.
PLCs are robust digital controllers made for the industrial environment. Some years ago, I worked on a facility and had my first contact with these peculiar controller called "PLC".
But, anyway, I will not waste my words saying something everyone here already know. It's really an excellent project that changed the way people look to electronics.
